Introduction: The instrument is used to detect corundum, glass, refractory materials, modeling materials, ceramics, glaze, graphite, carbon and other inorganic materials, thermal expansion properties of metal products for scientific research, teaching provide the necessary testing methods. Can complete the linear expansion coefficient, body expansion coefficient and draw the relevant curve. According to the needs of choice, no load or load test. Technical Parameters: 1, the highest temperature: 1000 ℃, 1400 ℃, 1600 ℃ by the customer choice. 2, heating rate: 0-20 degrees / min adjustable, microcomputer temperature control program. 3, automatically calculate the compensation coefficient and automatically compensate, but also artificial correction. 4, Even the computer automatically records, stores, prints the number , prints the temperature - the expansion coefficient curve. All experimental operations are computer interface is completed, easy to learn and provide a full set of software. 5, expansion value measurement range: ± 2mm. 6, measuring the swelling value resolution: 0.1um, automatic calibration range. 7, the sample range (4-15) × (40-150) mm (with the atmosphere on request protection, vacuum). 8, heating furnace up and down sliding sample loading and unloading. 9, loading range: 0-2000g adjustable. 10, the system measurement error: ± 0.1-0.5%. 11, the power supply voltage: 220V ± 10%, 2KW.
